" IMPROVEMENT IN TEMPORARY BINDERS FOR MUSIC, 6to- TO ALL WHOM 1T MAYCONCERN:

"3e it known that I, JOHN C. CLARKE, of Jersey City, Hudson county, NewJersey, have invented a new and useful Improvement in Yortfolio forNewspapers, Periodicals, Music, Ste.; and I dohereby declare that thefollowing is a full, clear, and exact description thereof, whchwillenable others skilled in the art to make and use the same, referencebeing had to'the accompanying drawings, forming part of thisspecification, in

which- Figure 1 is a view of my improved portfolio open, and showing inred lines themanner in -which the music, 55e., is attached.

Figure 2 is a cross-section of the same,closed and filled.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved portfolio, soconstructed and arranged that the periodicals, tc., may-be easilyattached, securely held, and readily removed, when desired; and itconsists in the combination of thev rigid metallic .back plate, havingcross-slots formed in its end, and thc hinged side plates, by which itis connected with the cover with each other, andpin the combination ofthe cord'or cords for securing the content-sof the portfolio in placewith the slotted back plate; the whole being constructed and arranged ashereinafter more fully described.

A are thesides, and B the flexible back of the portfolio, about theconstruction of which there is nothing new. C is a rigid metallic back,to the side edges of which are hinged the edges of the side plates D, asshown I in figs. 1 and 2. The side plates D are secured to sidesA of thecover by means of rivets, or in some other convenient and substantialmanner. In the ends of the hack plate C are formed cross-slots e', orholes, for the passage of the'cord E, by means of which the periodicals`music, or other contents of the portfolio are secured in place. n

- The .cord E may be continuous, that is to say it may be passed throughthe slot at one end of the back plate C, then along the said plate,through the slotat its other end, along the other side of thc plate, andso on, until enough turns have been made to hold the intended contentsof the portfolio. The cord E may be elastic or inelastic, as maybepreferred, and, if desired, instead of being continuous, each cord maymake but a single turn. The music, periodicals, duc., are attached bypassing them through a loop of the cord E, so that the said cord mayrest in'the central fold ofthe music or periodical, as shown in red infigs.1 and 2. When thus attached, the music or papers are read in theorder in which they are placed, in the same' manner as theconsecutive-pages of a book are read. i

I claim'as new, and desire to secure by Letters Patent- Il..v Thecombination of the rigid metallic back C, having cross-slots c formed ini`t, and the hinged side plates D with each other, substantially asherein shown and described and for the purpose set forth.

. 2.. The combination of the cord or cords-E with the slotted back plateC, substantially as herein shown and described and for the purpose setforth. Y l

3. The combination of the-slotted back plate C and hinged side plates Dwith the side boards A and back B of the cover, substantially as hereinshown and described and for the purpose set forth. l The abovespecification-of my invention 'signed by me, this 18th day of June,1867.'
